EDUCATIONAL DEVICE.

SPECIFICATION forming part of Letters Patent No. 663,287, dated December4, 1

Application filed November 18,1899. Serial No. 737,542. (No model.)

To ctZZ whom, it may concern:

Be it known that I, THOMAS L. MARTIN, residing at Lewisburg, in thecounty of Logan and State of Kentucky, have invented a new and ImprovedEducational Device, of which the following is a specification.

This invention is an improved educational device and is adapted for usein teaching writing, spelling, arithmetic, the fundamental principles oflanguages, or anything else that can be taught by copy.

The object of my invention is to provide a simple form of device whichcan be manipulated by a scholar under the direction of a teacher and onein which the copy will be placed in front of the pen or pencil.

The construction and operation of the device or apparatus are asfollows.

In the drawings, Figure 1 is a perspective view of my improved device.Fig. 2 is a top plan view, and Fig. 3 is a section on the line 3 3 ofFig. 2.

In constructing the device I employ a stand or frame A, composed of theside pieces a, connected by cross-rods a and a and said rod 0. also actsas a hinge-rod for connecting the frame Awith the forward section B,comprising the side pieces I) and connecting-rods b and h The sidepieces a are formed with curved seats a in which rests a cylinder 0, andpassing through said cylinder is a shaft D, upon which is wound theribbon E, upon which the copy is written.

The shaft D is operated by means of a crank F, and carried upon saidshaft outside the cylinder is a gear-wheel G, which meshes with anothergear H, mounted upon the end of a shaft H, journaled in bracket 72.,projecting rearward from the side pieces a. The ribbon passes outthrough an opening cin the front of cylinder and then forward anddownward between the rods 1) and b and around the roller 1) on rod bthen back under rod a and cylinder over a roller K, and is wound upon aspool H mounted on shaft H. The roller K is mounted on a shaft is,journaled in bracket It, extending from the sides a. By

turning the crank F the shafts D and H are revolved, and as the ribbonis Wound upon one it is unwound from the other, and the bars I) and Z)and roller K act as tension devices to keep the copy taut.

A small box or receptacle L is mounted upon the cross-rod a and in whichpens, pencils, and sundries may be kept. Guide-disks M M are mountedupon a shaft m, journaled between the sides Z), and similar disks N Nare mounted at the ends of the rollers K and H the purpose of said disksbeing to keep the ribbon straight as it is wound from one roller to theother.

The slate, tablet, or sheet to be written upon is slid beneath theroller I), mounted upon rod b and as the portion B is pivoted to theportion A said part B will move upward sufficiently to acom modate athick or thin slate or tablet. The roller thus always rests and pressesupon the slate-frame and assists in holding it fixed in place. The pupilmay place the Writing-point inside the roller b and it will thus benoted that the copy is directly in front of the writing point, while theroller b serves as a hand-rest. When one line is finished, the slate,tablet, or sheet can 4 be pushed under the roller 19 and another linewritten.

A device of this kind. saves a teacher a great deal of time and trouble,as one teacher can direct one hundred pupils to turn to a certain lineor page and copy the same, and it will only be necessary for the teacherto inspect the work.

While teaching writing Various studiessuch as spelling, arithmetic, andgrammar can also be taught, since a person constantly copying a numberof words or examples in arithmetic will be impressed with the manner ofspelling and the rule for doing said examples.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. An educational device comprising a main frame, ribbon -windingrollers which are geared together, asupplemental frame hinged to saidmain frame, so that it may be raised as required, and having guide-rodsarranged at its front end, one being higher than and in rear of theother, and a ribbon passing over said rolls and back to thewinding-rollers, substantially as shown and described.

2. An educational device comprising the frame, a cylinder fixed thereinand having a lengthwise slot in its front side, a rotatable crank-shaftpassing axially through said cylinder, a roller arranged parallel tosaid shaft, and meshing gears operatively connecting the cylinder andshaft, guide-rods arranged in the front portion of the frame, and aribbon wound on the shaft and roller, and passing intermediately oversaid rods, as shown and described.

3. The educational device comprising the main frame adapted to rest upona Hat surface, the ribbon-winding shaft and roller arranged therein, andthe supplemental 0r movable frame hinged to the main frame and havingguide-rods, one of which is located at
